I’ve been involved in several library remodels and building projects lately for public libraries in the 15,000-30,000 square foot range. My job is to help select self-check systems, and to implement RFID and automated materials handling technologies for the purposes of optimizing materials handling workflows. However, optimizing materials handling workflows is really about optimizing services to patrons. Selecting technologies and making recommendations about how to optimize their use is the easy part. The harder part is helping libraries transition from their traditional staff-based circulation workflows to self-service workflows which free up staff to focus on other patron needs without the constraints, and structure, provided by the traditional circulation desk model.
